Windows 7: Nvlddmkm.sys one day after freshly reinstalling system

Nvlddmkm.sys one day after freshly reinstalling system

The main reason I reinstalled the system is to not have Nvlddmkm.sys show up. One day after reinstalling, there it is again. Windows 7 Pro SP1 x64. How do I create and upload an error log?

Yes, it was a blue screen!
BTW, my PSU exploded this morning, I think this could have been the cause of the problem... I will buy a new power supply Monday.

Also, I remeber the PC beibg unusually noisy, VERY noisy, I assume it was the cooler inside the PSU that was problematic. It could be that the cause of the problem was hardware, not a driver or malware issue..

Yes mate it really could have been the problem but bit late to use my little check ditty for it. The noise could have been the cooling fan and or the caps going south as both can get extremely noisy when at fault. Thing is the PSU is one component very often forgotten when issues arise and it is always wise to just keep a check on the state of it as I have pulled some out that are so full of dust hair and general crud it isn't funny.

Now just a word of warning DO NOT ever attempt to disassemble a PSU unless you know what you are doing because inside there are lethally high voltages very similar to those used for resuscitating heart attack individuals and those defibrillator machines are designed to actually stop the heart in an attempt to get it back into a natural rhythm and the same happens if PSU's are handled by the unwary to foolish people.

See what the new PSU does to improve things but if you want you can attach BSOD dumps with these

Is the PSU dangerous to open even when completely disconnected from the computer? Does it have any internal charge? I wouldnt open it either way since its still under guarantee since its just 9 mts old, I might get a free replacement. But I think I will switch to another brand since this seems like garbage, no wonder when it costed around 15€...

Yes Stefan some can hold the charge for days and even when disconnected from any mains power supply.See pic
Now if you are in the market for a PSU then use this to find out what size you may need it usually exceeds what you need as a safety margin - you may add more components in the future
OuterVision Power Supply Calculator type in what will be in the machine and it automatically works it out for you and by the by get a good brand PSU it is worth it in the long run.
Myself I like Corsair, Thermaltake, Coolermaster, Seasonic - the one that you have looks to be oen of those awful OEM ones that come with the case.

A good article if you are interested is this https://en.wikipedia.org/wiki/Power_...unit_(computer) - there is a good pic of the 24 pin output volts should you need to know what is what.

WOW, I had no idea! I used to open old PSU when I wanted to remove dust... Never knew how dangerous that was haha!
Yes, I will consider Cooler Master or Thermaltake! Thanks for this info. I'll buy one tomorrow and report back on results.

Just as well you asked mate I have had some near misses myself while rigging some up for a power supply source for testing fans, spinner hard drives etc etc That is not encouraging you to do the same just best left alone really until you know exactly what you are doing with them.

Yep my particular favourite is Corsair to be honest but Seasonic are good. Having said that many are made by the same companies and I am guessing the the brand people are in control of the manufacturing specs so one brand made by Joe Blow may be more precisely made than another made by Joe

Anyway that calculator will show you what size you need to get.

Ok, I underestimated the prices of Thermaltake and Cooler master PSUs, by FAR! I can't afford those, so I bought this one:
Gigatron - ZEUS Napajanje 560W ZUS-560 - Napajanja za računare - Napajanja
So far, the computer works well and does not sound noisy, I would say that the problem is resolved.
I'll post the Bluescreen report.
